Overview

The StanfordExtra dataset contains 12k labelled instances of dogs in-the-wild with 2D keypoint and segmentations.It released with the ECCV 2020 paper: Who Left the Dogs Out? 3D Animal Reconstruction with Expectation Maximization in the Loop.

Instruction

• All annotations, segmentations and metadata are sourced in a single .json file for ease of download. However, you will also need to download the Stanford Dogs dataset to access the raw images.
• For segmentation decoding, install pycocotools

python -m pip install "git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI"

• The demo.ipynb code is trivial to adapt to work with the full StanfordExtra dataset, by editing the following lines to match with your Stanford Dogs download and your StanfordExtra download:

# edit this to the location of the extracted StanfordDogs tar file (e.g. /.../Images).
img_dir = "sample_imgs"

# edit this to the location of the downloaded full dataset .json
json_loc = "StanfordExtra_sample.json"
